Genesis 30:4-13

So she gave him her servant Bilhah as a wife, and Jacob went in to her. And Bilhah conceived and bore Jacob a son. Then Rachel said, “God has judged me, and has also heard my voice and given me a son.” Therefore she called his name Dan. Rachel’s servant Bilhah conceived again and bore Jacob a second son. Then Rachel said, “With mighty wrestlings I have wrestled with my sister and have prevailed.” So she called his name Naphtali. When Leah saw that she had ceased bearing children, she took her servant Zilpah and gave her to Jacob as a wife. Then Leah’s servant Zilpah bore Jacob a son. And Leah said, “Good fortune has come!” so she called his name Gad. Leah’s servant Zilpah bore Jacob a second son. And Leah said, “Happy am I! For women have called me happy.” So she called his name Asher.
